* Use log in tap package instead of fmt. * Moved api/pkg/tap to root. * Added go.mod and go.sum for tap. * Added replace for shared. * api uses tap module instead of tap package. * Removed dependency of tap in shared by moving env var out of tap. * Fixed compilation bugs. * Fixed: Forgot to export struct field HostMode. * Removed unused flag. * Close har output channel when done. * Moved websocket out of mizu and into passive-tapper. * Send connection details over har output channel. * Fixed compilation errors. * Removed unused info from request response cache. * Renamed connection -> connectionID. * Fixed rename bug. * Export setters and getters for filter ips and ports. * Added tap dependency to Dockerfile. * Uncomment error messages. * Renamed `filterIpAddresses` -> `filterAuthorities`. * Renamed ConnectionID -> ConnectionInfo. * Fixed: Missed one replace.
